Small ad-hoc wireless networks are becoming ubiquitous. Wireless protocols like ZigBee, ANT, and Bluetooth have been targeted towards small devices with limited capabilities. As the volume and sensitivity of data being communicated over these networks increases so does the need for security. The limited capabilities of these devices, however, means the standard in security is out of their reach. Cost...
Freshness is one of the most desired security properties of sensor network communication architecture. And sequence number is a common technique that is used as a freshness identifier to achieve freshness transmission. However, due to characteristics of wireless sensor network, such as resource-constrained and attack prone, it is vulnerable and energy-expensive to transmit sequence number directly...
Sensor networks are expected to be used at anywhere in the near future and recently their security problems have been rising. Due to the limited computing power of senor nodes, it is impossible to use asymmetric cryptography approaches for the session key establishment or to apply advanced encryption method such as AES and DES for the data encryption. In this paper, therefore, we propose a key establishment...
